The CoinDesk Bitcoin Price Index (XBX) leverages real-time prices from multiple constituent exchanges to provide a representative spot price of Bitcoin in US dollars and is calculated once per second. Each constituent exchange is weighted proportionally to its trailing 24-hour liquidity with adjustments for price variance and inactivity. Known for being the longest-running, and most trusted benchmark for bitcoin, XBX has been in continuous operation since 2014 and serves as the benchmark for approximately $22 billion of AUM in investment vehicles as of October 31, 2023.
Given the potential for anomalies or manipulation at individual exchanges, constituent weights may dynamically adjust using CoinDesk Indices proprietary Constituent Weighting Adjustment Algorithm (CWAA). The algorithm is designed to calculate a real-time index that is an accurate and reliable reflection of the market price of each digital asset, using multi-sourced spot prices and dynamically reduce the weights of individual exchanges with lower liquidity, inactivity, and higher price variance.
